The Scrooge-bahhumbug-Crachits-Tiny-Tim-Marley-three-ghosts-Godblessuseveryone story is nearly as familiar as the Nativity. In fact, some of our favorite tellings take great liberties with the story, like the Muppet version or the movie “Scrooged.”

But it is also promoted as a proper holiday tradition, faithfully executed, every year at Indiana Repertory Theatre. So, how do they keep it reliable, yet unique?

Start with the Tom Haas script, which hews fairly closely to the source material. Under director Janet Allen, have the cast tell the story as they portray the events, in a pudding-smooth blend of narration and action.

Keep the set simple, as scenic designer Russell Metheny has done. The dominant feature is the drifts of snow absolutely everywhere – pure white like holiday magic, yet also a constant desolate reminder of the dangerous cold of a Victorian English winter. Setpieces drift in and out, and a simple large frame sees duty in many ways – a doorway, a mirror, a passage to what comes next.

Cast some of the best talent in Indy, including a number of IRT regulars, starting with the brilliant Ryan Artzberger as Scrooge. Other familiar faces include Charles Goad, Mark Goetzinger and the luminous Millicent Wright. You may also recognize Emily Ristine, Scot Greenwell and Jennifer Johansen. Then there are Jeremy Fisher, Charles Pasternak, Ashley Dillard and Joey Collins. And mix in some great young talent as well, such as Tobin Seiple and Maddie Medley, who take turns as Tiny Tim.

Present it all in a single movie-length performance, submersing the audience into the story until we can’t help but get caught up in it. Of course, we know what’s going to happen next, but with the spirit of live theatre taking us along, we don’t just watch the play, we experience it.

I feel like a bit of a Scrooge sometimes, thinking of things like the Dickens story as stale and overdone; but having seen what IRT does with it, I now see why all those who go back every year enjoy it so much. You, also, might want to consider adding this show to your list of cherished holiday traditions.

Performances continue through Christmas Eve at the IRT, 140 W. Washington St. (near Circle Centre) in downtown Indy. Get information and tickets at www.irtlive.com.
